render pdfpage to bitmap (=raster) with given resolution or image size ?

Hi SF & community,

I have a typical pdfpage added via pdfdoc.Pages.Add();
and then populated with syncfusion tools & functions

How can I render that page to bitmap with either a given resolution (ppi) or total image Width/Height size ?

Hi Fabrice, 
Thank you for using Syncfusion products. ExportAsImage can be achieved only through the PdfLoadedDocument.  
Method 1: 
The PdfDocument cannot be directly converted to bitmap. The PdfDocument need to be stored in stream and we need to convert the stream as PdfLoadedDocument. And then the pdf can be converted to bitmap. 
Please find the sample from the below link, 
Method 2: 
Please find the code snippet to convert the PDF page to Image using PdfLoadedDocument, 
PdfLoadedDocument doc = new PdfLoadedDocument(@"Barcode.pdf"); 
Bitmap image = doc.ExportAsImage(0, new SizeF(doc.Pages[0].Size.Width, doc.Pages[0].Size.Height), true); 
Please find the sample from the below link,
